This invention relates to eyeglass construction and more particularly to a mountingv for a nose pad.

One of the objects of this invention is to provide casionally the substitution of pads is desirable and this should be accomplished without disturbing the position of the pad supporting arms as they are usually adjusted to their proper positions (Figure between the sides of arm II and the inner sides of mounting I2, and spaces 21 and 28 (Figure 6) between the top and bottom or arm I I and the top and bottom of mounting I2, for a purpose hereinafter described.

Bottom I9 of mounting I2 may be secured in any suitable manner to nose pad I3 (Figure 1) so that the top portion I8 of the mounting faces inwardly of loop I5 when mounted. The mounting and nose pad thus comprise a unit which may be readily assembled with arm I I in a manner to be described. Referring to Figure 3, arm II is inserted through mounting I2 until the end portion I6 of the arm projects from the right-hand end of the mounting, as viewed in Figure 3. Tongue 24 of mounting I2 is positioned directly over notch I1 and may be bent into notch H (see Figures 4 and 6). When tongue 24 (Figure 6) is thus bent, its under surface 24a is parallel to but slightly spaced from surface Ila of notch I'I. Also, the bottom edge 24b of the tongue (Figure 4) rests on the bottom surfaces of notches 22 and 23, and the right-hand edge of tongue 24 (Figure 6) lies behind and spaced from the vertical surface I'Ib of notch II. When the tongue is so positioned, arm I I is positively retained within mounting I2 and is movable universally therein but only to the extent provided by openings 25, 26, 21 and 28 (Figures 5 and 6) and by the space between tongue 24 and notch surface I'Ia, as well as the beveled surfaces I10 and H11. These spaces provide for ample movement between nose pad I3 and arm II (Figure 1) to permit the nose pad to be comfortably worn, but prevent excessive movement between the pad and the arm which might cause excessive wear or discomfort.

It should be noted at this point that mounting I2, and accordingly nose pad I3 may be secured to the end of arm II without in any manner disturbing the position of the arm. Hence, in a case where substitution of pads is necessary, pad I3 is readily attachable to arm II without disturbing the originally adjusted position of the arm.

Quite often nose pads become damaged or excessively worn so that replacement thereof is desirable. Removal of my pad I3 from arm II is readily effected by inserting a suitable tool, such as a knife, into slot 22 or 23 (Figure 4) and prying tongue 24 upwardly, whereupon arm Il may readily be withdrawn from mounting I2'without disturbing the position of the arm. The nose pad may then be repaired and replaced as noted above, or a new nose pad may be assembled.

Because of the rectangular form of arm II in mounting I2, it is impossible for mounting I2 to pivot about arm II beyond the extent permitted by spaces 25, 26, 21 and 28, and beveled surfaces I I0 and lid. Excessive rocking movement, axially of arm I I, is also limited by these spaces, the size of which can be varied as desired. The generally rectangular shape of arm I I and mounting I2 further results in a neat, compact appearance, and effectively provides a simple mounting by which the nose pad can easily be attached to or detached from the eyeglass frame. Also, slots 22 and 23 (Figure 2) in mounting I2 provide the integral tongue 24 which is easily depressed into notch II (Figure 4) of arm I I, and which cannot be inadvertently disengaged.

Thus it may be seen that I have provided a nose pad mounting which effectively and practicably attains the several advantages noted hereinabove, and obviates the difficulties referred to.

As many possible embodiments may be made of the above invention, and as many changes might be made in the embodiment above set forth, it is to be understood that all matter hereinbefore set forth, or shown in the accompanying drawing, is to be interpreted as illustrative and not in a limiting sense.

I claim:

1. In eyeglass construction, in combination, a supporting arm having a free end with a notch therein, a nose pad, and a hollow mounting member secured to said nose pad and fitting over said arm, said mounting having slots in its sides to provide a top tongue portion bent down into said notch and said mounting being larger than said arm to provide play therebetween.

2. As an article of manufacture, a nose pad having a mounting part comprising a four-sided open ended part secured thereto with registering slots in its opposite side walls adjacent one end thereof to provide a top portion in the form of a tongue adapted to be bent into said slots to interfit with a notch in a supporting arm on an eyeglass frame.

3. In eyeglass construction, in combination, a nose pad, means forming a support for said nose pad, said support having a notch formed in a portion thereof, a box-shaped mounting part secured to said nose pad, said part having registering slots formed in the side walls thereof to provide an integral locking tongue thereon, said support being insertable through said mounting part to a position wherein said tongue may be bent into said notch to secure said mounting part to said support.

4. In eyeglass construction, in combination, a nose pad, an arm support for said nose pad having a free end, said arm having a notch with a squared edge adjacent said end and its bottom sloping upwardly from said squared edge, and a hollow mounting part secured to said nose pad and shaped to fit over said arm, said mounting having a pair of slots formed in the sides thereof to provide a bendable tongue on its top side whereby said tongue may be bent downwardly into said notch to secure said nose pad to said arm support.

5. In eyeglass construction, in combination, a nose pad, an arm support for said nose pad having a free end, said arm having a notch with a squared edge adjacent said end and its bottom sloping upwardly from said square edge, and a hollow mounting part secured to said nose pad and shaped to fit over said arm, said mounting having a pair of slots formed in its sides so that its top portion extends down into said notch with the end of the top portion adjacent said squared edge of said notch.
